NPPTL Respirator Assessments to Support the COVID-19 Response
Decontaminated Respirator Assessment Request
Disposable filtering facepiece respirators (FFRs) are not approved for routine decontamination and reuse as standard of care. However, FFR decontamination and reuse may need to be considered as a crisis capacity strategy to ensure continued availability. CDC has released Decontamination and Reuse of Filtering Facepiece Respirators using Contingency and Crisis Capacity Strategies, which summarizes relevant studies looking at different methods of decontaminating filtering facepiece respirators (FFRs).
NPPTL staff is conducting a limited assessment to determine the particulate filter efficiency of N95 respirators that have undergone a decontamination process using NIOSH Standard Test Procedure TEB-APR-STP-0059pdf iconpdf icon (STP-0059). All NIOSH-approved N95 respirators are approved using STP-0059. As such, this assessment will allow NPPTL to assess the particulate filter efficiency of NIOSH-approved N95s that have been subjected to a process of decontamination. This assessment is not to determine the effectiveness of the decontamination procedure. Instead, it is designed to determine the effects of the decontamination process on the filtration performance of the respirator.
Only new, unused N95 respirators that have undergone a decontamination process will be accepted for assessment. Respirators that have been used or otherwise contaminated with any pathogenic microorganisms before the decontamination process WILL NOT be accepted.
If you are interested in having NPPTL assess the filtration performance of your decontaminated N95 respirators, please complete the following form. If assessment of multiple models of respirators is being requested, this form should be completed for each model.
